ok here is the issue I would like to know if anyone has ran into this situation at all....ok when I rev the motor it revs up to 5000.......so I I checked everything on the car.... I swaped distributors, I swaped out tps sensor, I swaped out the map sensor, I swaped out ecu and spark wires...it doesn't bogg when I rev.. it doesn't pull no codes at all starts up fine idle is good as well. its a 98 LS motor in a 92 vx hatch...right now I'm leaning to start checking the fuel and checking if it will be a fuel issue instead of a sensor issue.........but I wouldn't think it would be a fuel issue cause if it was that issue.... would it end up boggin? all I remember from yesturday was when I was heading home of a sudden it start to choke real bad and act like it wanted to die....then of sudden it went back to normal....????? I'm lost...someone help meh...

 

My car once wouldn't rev above 4600. I ended up adding a ground wire from the ecu to the chassis and it fixed the problem.
